Commitment to purity
We source exclusively from ISO 9001 certified manufacturing facilities. Every batch undergoes rigorous High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) testing to verify identity and purity before it reaches inventory.
- Guaranteed sequence accuracy: verified via high-resolution mass spectrometry to confirm exact peptide chain formation.
- Optimal counter-ion: synthesized as TFA or acetate salts based on specific stability and solubility requirements.
- Amber UV-shielded vials: lyophilized products protected from light degradation and environmental contamination.
